Printer Friendly Forum Posts - 07 mustang, python 990

I just got my alarm today, I will be installing it tomorrow with one of my installers help on my 07 mustang. I got the python 990 alarm, r/s, 513t mini piezo siren(very loud), 556sw r/s bypass coded, and 689m neutral bypass for r/s. Are their any wires I can connect and solder today to help set up for the install tomorrow. I'm curious how all these wires connect to each other or do they just connect to wires in the car? Thanks

Where should I mount my blue led light? I am thinking about putting it in the defroster opening above the driver ac vent. I don't want to drill a hole in my car so when I sell it, I don't have to buy a new light bezel thing.

Isn't there a switch blank adjacent to the radio? you can access it from the glovebox area.

No on my car I don't have any available switch blanks above the radio. I might just not install the light since their isn't a good place to put it.

Ok I have been working on this alarm for two days straight and still not close to being done. I'm doing it pretty much on my own with some help when I get stuck from some of the installers. Today I tied all the wires together on my brain. I mounted the siren in the engine bay, put the brain in the car, mounted the led and antenna, and started to run the wires to where they need to be. I also stripped some wires and tested them to make sure they were the right wires. I tied all 3 of the red power wires together and was planning on tying them to the 12v constant wire. But someone said I should run a fused line to the battery. I would rather keep everything in the car so a thief can't just pop my hood and take out the fuse and then he can take his time stealing my car. Also what wires do I have to use a resistor for? I'm still unclear what else I need to do.Thanks

ive always used the 12v from the ignition and never had a problem
(some stores require that the installers run a separate 12v from the battery)

No resistor required, the resistor pack that DEI included is for the 451m just in case the car requires it. Just save it.

Note: You Always Dont Get What You Pay For.

Just wondering if it would hurt anything if I connected every wire to something in my car. I have a python 990 alarm r/s 07 mustang. I think I am gonna pull my wires and rerun them to the sjb just so all the wires are together and neater. Can I hook up the factory arm, disarm if I don't have a factory alarm..will it do anything if I do or don't? With cutting the starter wire in half for the r/s will this make the car not start if my alarm isn't on or getting power or what?

I guess I need two relays for my alarm r/s. One for the trunk release and one for the trunk pin to change its polarity.I am using the 451m that came with my alarm as a relay for my trunk release. The trunk release is a -RED / white wire from alarm brain,-WHITE/ violet on my car. So how do I set up the relay for it?
For the Trunk Pin Relay...alarm is -blue, car is +WHITE/ yellow. How do I set that up to change the polarity? I have a 4 pin relay and the 451m 5 wire relay. Diagrams would greatly help me out. Thanks

I have two relays for my alarm r/s. One is the 451m that came with my python 990 alarm and another is a 4 pin relay from radio shack. One for the trunk release and one for the trunk pin to change its polarity. I am using the 4 pin relay for my trunk release. The trunk release is a -RED / white wire from alarm brain,-WHITE/ violet on my car. So how do I set up the relay for it?
For the Trunk Pin Relay I will use the 451m which has like 8 wires coming out of it. Alarm is -blue, car is +WHITE/ yellow. How do I set that up to change the polarity? Diagrams would greatly help me out. This is for a 07 mustang. Thanks

I am thinking about using the 451m that came with my alarm as a relay for my Trunk pin. It has 8 wires coming out of it. I need it to hook up to -blue(trunk pin from alarm brain) and +WHITE/ yellow(car trunk pin) Any ideas?

the 451m can be used as 2 seperate relays (I use them quite often on chrysler/dodge vans for parklights as well as 2nd start). The violet/black(87), GREEN/ black(30), and WHITE/ black(87a) are controlled with the red (85) and green (86) small gauge wires. While the violet(87), blue/black (87), and BROWN / black(87a) are controlled by the red(common 85) and blue(86). I am pretty sure on the actual relay pins, but they could be wrong. If so, the only thing that would be wrong are the 87 and 30 may be switched. HTH

For your trunk pop, hook up the violet/black fused connection (keep violet and violet/black connected at the fuse) to 12v, blue/black to your trunk release wire in the vehicle(+), red to 12v, and blue to the brain's trunk release output (-)

Thanks for the help. Quick ? I already hooked it up today a different way. Someone from the circuit city forums told me to hook it up this way. Can you tell me if he's right or wrong? I don't know who's right? He said use small red to (+)WHITE/ yellow car trunk pin. small blue and Large purple's to ground. Large blue to alarms (-) blue. I really only needed this relay to change the polarity on the car side from a (+) to a (-). I work at Circuit City too as a Mobile salesman store 0571 Tampa Fl.

Here's a couple ways to hook up the 471m to the trunk pin to change its polarity. Small red to (+)WHITE/ yellow trunk pin. Small blue and Large Purple to ground. Large blue/black to alarms (-)blue.
OR...
small red and purple to 12v. Large blue/black to (+)WHITE/ yellow. small blue to (-)blue alarm. Please let me know if I am wrong.

Oh... sorry. I thought u were trying to use it as a trunk release, not trunk pin. If you need it for switching voltage to trigger the alarm when the trunk is open, then the diagram he gave you is correct. Sorry for the mis-information... i should learn how to read things first.. lol.

I just finished my alarm, python 990. Led will blink 3 times, pause, then blink 1 time, pause, then repeat, is their something I forgot to setup or what? It stays on even when I start the car and drive, its very annoying. Any ideas?

Check the ignition wire for proper connection?

Jamaica home of the worlds fastest man.

So even if I don't have the R/S hooked up I still have to have the ignition wire hooked up? Guess thats the problem lol.

Now I want to hook up dome light supervision..guess what I need another relay. This is getting annoying. I will have used 3 relays and a 10k resistor on my alarm by the time I'm done. Does every alarm usually take like 3-5 relays?

From the remote start ribbon you must connect the yellow wire to ignition.

Basically, the alarm is flashing you the zone that was violated. It will do this until the ignition is turned on. If you don't have the ignition wire tapped then it will never reset, ever!

Ok figured it out. Hooking up the ignition wire turned it off. Thanks for the help.

I haven't hooked up my ground when armed wire yet, Where does it go, to the starter wire or what? I have a python 990, in a 07 mustang.

The Python 990 already has a built in starter kill on the relay pack. What you must do is cut the starter wire and connect the purple wire of the relay pack to the starter side and the green wire from the relay pack to key side and your all set. In this case you wouldn't need the orange wire since the relay pack already does it for you.

Ok I decided I don't need the domelight supervision. Cause once I open the door the light turns on anyways. So I used 2 relays and one resistor for my 07 Mustang. Thanks for all the great help and tips. I couldn't have finished my install without sites like this.

I have a 07 mustang, it doesn't have a factory alarm, just keyless entry. I added a python 990. Should I have hooked up the fact. alarm disarm wire lt. GREEN/ black Or not? The alarm works fine without it. Just wondering. Also where would I hook up the remote start act. input from the brain (-)WHITE/ blue wire?

you do not need to wire up the factory alarm disarm wire beacuse you dont have a factory alarm. just hook up your lock and unlock.

also, im not sure wat your talkin about "remote start act. " if you are looking for awire you connect to acc, to tell the unit the key is in, it would be a positive wire (+), what is the model or name of the unit?

You leave that WHITE/ blue alone, tape it up.

Ok thanks guys I will just tape those two wires up.

My led keeps blinking 3 times, the installer told me the shock sensor is set to high, but how do I turn it down? I see where I put the small screwdriver, but which way do I turn it, it doesn't have any arrows? Thanks

Big problem. My alarm has been going off like every 20 mins. I tagged my - door trigger to the dome super wire, I also have a 10k resistor with the other end to a constant 12v battery source to prevent falsing, but its not working. Alarm pager says the door trigger is what is setting off the alarm. Any ideas?

Bump any ideas. Door trigger keeps going off about every 20 mins. Very annoying. Also how do u change the settings on the shock sensor, like which way do you turn it to go up in sensitivity or down..no arrows on it.

clockwise = higher sensitivity

The dreaded directechs 1076 will answer your door trigger problem

the Directfax#1076 is the diagram to prevent the GEM from pulsing your door trigger input, if I remember correctly.

Simply, you need diodes isolate the path so there arent any feed from the GEM side to your door trigger input.

How is everything else?

Btw, does ford still use GEM?

"The two most common elements in the universe are H+ and stupidity" (Ellison).

yes, especially here, (use of Gem box, except mustang box is bigger, I'm thinking of the black box on r/hand wheel arch inside car. if 07 mustang pms me with an email address i can send it from my document file.

Well I had to replace the 10k resistor I put in line with the dome light supervision wire and a constant 12v source on the other end. It seems to be working. I guess the last resistor broke somehow, that's why it was going off. Now I'm looking for a better solution. How do I use a diode and what type do I buy? Or how would I hook up a resistor to the dome light super for the door trigger? Man this alarm stuff is so confusing.

Trust me youre not the only one. When I first installed on an ford w/ the GEM module, I didnt know a clue until the fellows here helped me out.

Just hang on a lil more.

Use 1n400x series (1n4001, 1n4002, ect..)

Ebay has them 1000pieces for 10bucks or so...

"The two most common elements in the universe are H+ and stupidity" (Ellison).

Well I tested my alarm today. Everything works like it should except when I opened my trunk to trigger the alarm, it paged my remote that the trunk and hood were opened? Any ideas? I have a Grey wire going to the hood pin, and they don't share any common wires or anything, Why would my alarm say both were open? When I opened the hood to trigger the alarm only the hood open icon was received on my pager.

So what wire on the brain is the trunk trigger?

brain trunk trigger is -blue, the hood pin was a -gray wire

Have you used factory hood switch? This sits on ground when shut and open circuit when hood lifted; you will need to fit another switch. I believe the trunk switch is pos, you will need to flip the polarity to neg (Check these two)

I didn't use the factory hood switch. I connected the alarms -gray wire directly to my pin switch under my hood.

I already used a relay for the trunk pin/trigger alarm was -blue connected to cars +WHITE/ yellow(I used the 451m relay for this. Small red to +WHITE/ yellow in car, Small blue and Large purple to ground, Large blue to Alarms -blue.)

I also used a relay for trunk release, but don't remember how I hooked it up. car side was -WHITE/ violet, alarm was -RED / white.

Never mind, I had it set up wrong on my lcd remote pager settings. I had it set to say trunk and hood were open, instead of just trunk. So everything works now. Thanks for the help.

I have another ? about my trunk release wires. I just disconnected the relay and touched the two wires together for trunk release and it works. Would their be any problem with just connecting these wires, or do I really need to keep them on the relay? Does it need the relay to prevent falsing?

I hooked up my dome light supervision to a relay, but the lights only work sometimes. I have a 12v constant source tied to a 10k resistor on the dome light wire in the car(to prevent falsing, I also used it as my door trigger) Would this be causing it to work sometimes and fail most of the time?

I just tried using a relay for the door trigger. I hooked it up like this 86 to (driver door pin GREEN/ black), 85 to 12v, 87 to ground, 30 to -green alarm door trigger wire. When I had the door closed it paged me that it was open. When I opened the door it said it was closed. Any Ideas? I really need to get this alarm working. The door pin doesn't work and the domelight supervision doesn't work right either. Please help me out.

Check the door trigger initially, see that it goes to ground only on opening the door; if thats OK then you are looking at an alarm problem or something is touching ground on your alarm. Relay is correctly wired but not needed, try a diode between your wgreen wiring connection and the CPU in R/H kickwell with stripe on (1N4001) facing the connection.

Ok I just disconnected the dome light relay cause it doesn't work right(I think because my car has a delay in the domelights)

With the two individual door triggers I hooked both of them up to the relay. But they don't work. Keeps paging door is open when its actually closed, and says closed when both doors are open. I used driver door +GREEN/ black pass door +YELLOW /GREEN. They are positive cause when doors are closed they are at 0 and when the door opens they go to 12v. Any ideas, maybe I need to hook up the relay differently since they are + and not negative like the dome super wire?

If they are positive, join them via diodes, band towards alarm diode type 1N4001 and join to alarm's PURPLE wire.

Still not working: I'm starting to get wized off with this stupid car. I cut both door trigger wires. Put a diode inline with each of them, then another diode to the alarm positive door trigger. First I had the bands facing the door trigger(not the bcm end) and the alarm diode band facing the door trigger side of the other diode. Didn't work, it kept my radio on when I opened the door and didn't show anything with door open or closed on the alarm. I retested these wires. They are at 5.6v closed and 11.6v open on vdc mode of my voltmeter. (they are normally close type, rest at ground with door closed, and go to open circuit with door open)

then I switched the diodes to face the other way, with the band facing the bcm and that didn't do anything on the alarm, it also gave me door ajar warnings when I started the car. Any Help would be greatly appreciated. Thanks

i saw a chart and it states that you need 2 1a diodes and 2 1/4w & 47kohm resistors. Tag both wires and diode isolate them to connect to positive door trigger which is purple. Do not put wire in between trigger but put it between wire that connects to alarm. Now, before the diode is in place you would connect a wire to 12v and tag that one to the door triggers and between it you put a 47kohm resistor for both wires and you should be done.

The resistor was used when I first had it hooked up to cars dome super wire. I used a 10k resistor, one end to 12v constant and other to car dome super wire. It worked but the resistor broke, and made my alarm go off every 20 mins. so I was looking for a better way to hook it up. I tried relays, and today tried double diode isolation. Neither worked. I had it hooked up the way you said to the dome super wire. That worked. But when I tried hooking up the two individual door triggers nothing works. Maybe they aren't the right wires or something. Door open it goes to 11.6volts and door closed stays at about 5.6 to 3.9volts. Maybe my delay on the dome light staying on is messing it up or something.

read my edit post above

How did you edit, this site won't let me edit my posts?

Anyways I used 1n5406 diodes, its what my installers gave me, not sure if they are too big or not? Also I did use the positive purple wire from the alarm to the cars door triggers, which I think are positive, but not to sure since every time I test them the voltage changes.

I don't think I want to use diodes and resistors, if anything I will just go back to the one 10k resistor on the dome light super wire and use the -green alarm trigger wire.

What makes you think this will work?

I have a feeling we are running around in circles here; the 10k is an old trick to smooth out the surge from CPU's waking up, its long been superceeded by the 1070 diode trick, the diodes as I stated in an earlier post should have been 1N 4001 not 1N5401, WHERE DID YOU PICK UP YOUR DOOR CONTACTS?

I know the 10k resistor works because thats how I first had it set up. Until the resistor broke and made my alarm go off every 20 mins. So I am looking for a better solution here.

The door triggers I used are driver door lt.GREEN/ black at sjb black 26 pin plug, pin 2 Pass door yellow/lt.green at sjb black 26 pin 6.

I just hooked up the alarm purple wire to the driver door wire without a diode or anything..just directly connected it, and it seems to be working with the alarm not going off every 20. I will test hooking up another wire to both door wires and see if it still works. If not I just got some 1n4001 diodes at work today and will use those if the other way doesn't work.

Also with my dome super relay. When I arm my alarm the dome lights stay on for a delay of 20 seconds...is their a way to get them to shut off at arm, also most of the time they don't even turn on when I unlock my alarm. Any ideas?

Today I finished the install. I used 2-1n4001 diodes with the bands facing the +alarm door trigger wire. The other two ends connected to the individual car door triggers. The alarm works great with no falsing at all.

The domelight super relay works about 25% of the time, not sure what's up with it, maybe my mustangs delay messes with it turning on and off.

Thanks for all the help guys, I definitely couldn't have done the install without your guys help.
